The Carnegie Library of Reims is a public library built with money donated by businessman and philanthropist Andrew Carnegie to the city of Reims after World War I. Reims was one of three "front-line" cities to be given a Carnegie library, the other two being Leuven and Belgrade. Built in the 1920s, it combined the mission of heritage conservation and of reading public library. Until 2003, the Carnegie Library was the main library of Reims.
